Lessons on Waves, Light & Sound
| Intro to Waves
|This lessons examines some of the key principles and vocabulary applying to waves.
|Some very clear simulations of waves occupying the same place at the same time:
|Reflection of Waves
|Simulations of a pulse striking a new medium and a periodic wave striking a new medium.
|The Origin of Light
|This lesson examines where light comes from at the atomic level. It shows both photon creation and photon absorption.
| Movie &
|Doppler Effect Lab
|This interactive lab allows you to see the Doppler effect and experiment with aspects that affect the Doppler effect. Created by Raman Pfaff.
|Interference Beat Frequency Lab
|This interactive lab allows you to hear and experiment with the beat frequency created by the interference of two waves. Created by Raman Pfaff.
|Interference Patterns Lab
|This interactive lab allows you to overlap two patterns to produce a third "interference" pattern that would apply to light, sound or moir� patterns.
Created by Raman Pfaff.
|Patterned Array Lab
|This interactive lab allows you to experiment with a patterned (phased) array to see the effects of interference.
Created by Raman Pfaff.
|This lesson page has many real life examples of Resonance at work.
|Animations & Video
|Resonance in a Tube
|Here are a couple of lessons related to resonance in an open tube or closed tube.
|Animations, Simulations & Explanations
|Single Slit Diffraction Lab
|This interactive lesson illustrates the basic principles behind single slit diffraction.
|Double Slit Diffraction
Dialog on Double Slit Diffraction (Java)
|This lesson illustrates the basic principles behind double slit diffraction.
|This lesson demonstrates what polarization of light is and how a polarizer can be used to remove some orientations of light.
|Explanation & Movie
|A nice video demonstrating that a mirror doesn't reverse left and right, only forward and back.
|Explanation and animations of refraction
|Lesson & Images
|Index of Refraction
|This lesson illustrates the concept of index of refraction, Snell's law, and critical angle.
|Frequency, Wavelength, Energy of a Wave
|This is a drill and practice activity. You will be given the frequency, wavelength, or energy of a wave and be asked to calculate the other two.
|Drill & Practice
|Reflection & Refraction
|This interactive Java applet allows you to adjust an incoming ray of light and observe reflection, refraction, and internal reflection. It also allows you to switch mediums by Walter Fendt
|Reflection & Refraction (explained by Huygens' principle)
|This lesson shows the basic concepts of reflection and refraction but explains it from the point of view of Huygens' principle.
Created by Walter Fendt.
|Prism & Refraction Lab
|This interactive lab allows you to experiment with a prism and light source with different colors. Snell's law and the index of refraction are also addressed.
Created by Raman Pfaff..
|Dispersion Through Plane Glass
|This interactive lesson allows you to manipulate light passing through a plane piece of glass.
|Total Internal Reflection Lab
|This interactive lab allows you to explore the concept of the critical angle and total internal reflection. Also applies concept to diamonds and fiber optics.
(Java) Lab & Lesson
|This lesson demonstrates many of the concepts based on spectroscopy. The visible spectrum, emission spectrum, absorption spectrum, and blue & red shift are all shown.
|Pictures & Descriptions
|A collection of multiple choice questions providing immediate feedback.
|Multiple Choice Practice
|Optics Lesson Collection
|This contains many lessons related specifically to optics.
